I notice you've asked for definitions of a number of things, lately. In case you're interested in finding some of them yourself, I found information by simply doing a Google Search for definitions.
Tracking tools give online business demographic information about visitors/buyers on their sites. This allows them to tailor advertisements, emails and products that are most appealing to the "general/average" consumer. There is a detailed article about various marketing strategies at
A C Neilsen.
This is from within that article:
"Identify Demographic Trends According to a Client-Defined Sales Area Definition
ACNielsen's Custom Scantrack Demographic Service provides demographic information on client-defined sales areas accessed via a proprietary database. This service enables users to identify demographic trends according to the client's defined sales area definitions.
Manufacturers who want to target their brands to consumers based upon their custom geographies will benefit from this service. The custom geographies and enhanced facts give users a better understanding of demographic data based on their own sales area definitions.
The Custom Scantrack Demographic Service helps you to:
Enhance your competitive position with more targeted marketing by custom geographies.
Supplement and enhance Scantrack and/or Super Scantrack, Drug, Mass and Convenience Track investments.
Perform more robust CDI and BDI analyses with custom geographies.
Available in the U.S."
